What this research studies

If you are an older adult needing hip fracture surgery, doctors would randomize you to either monitored anesthesia care with surgeon-delivered local anesthetic injections (MAC-STILA) or standard general anesthesia. MAC-STILA uses carefully titrated IV sedation that preserves spontaneous breathing while the surgeon injects local anesthetic directly into the surgical site. The team will first build consensus on how to perform MAC-STILA across six hospitals, then enroll 140 patients and stratify them by baseline cognitive status. Researchers will track the incidence and severity of postoperative delirium and compare recovery between the two groups.

Who could benefit from this research

Good fit: Ideal candidates are older adults admitted for surgical repair of an acute hip fracture who are medically eligible for either monitored sedation with local infiltration or general anesthesia.

Not a fit: People without hip fractures, those who are not surgical candidates, or patients who require immediate general anesthesia or have contraindications to local anesthetic infiltration may not benefit or be eligible.

Why it matters

Potential benefit: If successful, this approach could lower the rate and severity of postoperative delirium and reduce anesthesia-related complications in older hip fracture patients.

How similar studies have performed: This specific MAC-STILA combination is relatively new and not widely tested, though some smaller studies of regional or lighter sedation techniques suggest possible reductions in delirium.
